Aelenei, Laura Elena; Aelenei, Daniel; Romano, Rosa; Mazzucchelli, Enrico Sergio; Brzezicki, Marcin; Rico-Martinez, Jose MiguelABSTRACT: Adaptive building envelopes can provide improvements in building energy efficiency and economics, through their capability to change their behaviour in real time according to indooroutdoor parameters. This may be by means of materials, components or systems. As such, adaptive façades can make a significant and viable contribution to meeting the EU´s 2020 targets. Several different adaptive façade concepts have already been developed, and an increase in emerging, innovative solutions is expected in the near future. In this context the EU initiative COST Action TU 1403 aims to harmonize, share and disseminate technological knowledge on adaptive facades at a European level. According to the definition given by this COST Action, an adaptive façade is a building envelope consisting of multifunctional and highly adaptive systems that is able to change its functions, features, or behaviour over time in response to transient performance requirements and boundary conditions, with the aim of improving the overall building performance. In order to explore the available and emerging technologies focusing on adaptive façades, Working Group 1 of the COST Action undertook research to form a database of adaptive façade case studies and projects structured in accordance with a simple classification – materials, components and systems. In addition to this, details of the purpose of the systems/components/materials with adaptive features and the working principle of each technology were also collected together with data regarding design practice, technology readiness, and economical aspects, among others. The information was collected with the help of a specific online survey (structured in the following main sections: detailed description - metrics- characterization- economic aspects – references). The database includes 165 cases of adaptive façade systems, components, and materials that allowed a variety of analyses to be carried out. According to the classification adopted within WG1 (materials, components, systems), each of the classification terms are introduced together with examples from the case study database in the following sections. This volume ends with a section dedicated to future developments, where different issues are addressed such as embedded functionality and efficiency amd biomimetic inspirations. The importance of adaptive façades through their flexibility, and intelligent design within the context of smart cities is also discussed.
- Definitions of Positive Energy Districts: A Review of the Status Quo and ChallengesPublication . Albert-Seifried, Vicky; Murauskaite, Lina; Massa, Gilda; Aelenei, Laura Elena; Baer, Daniela; Krangsas, Savis Gohari; Alpagut, Beril; Mutule, Anna; Pokorny, Nikola; Vandevyvere, HanABSTRACT: This paper presents an overview of PED definitions used in five prominent EU programmes and nine PED-relevant projects across Europe. By drawing similarities and finding discrepancies between them, the paper aims to identify the gaps and challenges in existing work. Through systematic comparison, the paper recognises common traces and differences between existing definitions. The main challenges include the definition of PED boundaries, the method for calculating energy balance, the scope of non-energy matters and the assessment of qualitative requirements. As the PED definitions are to be applied to locations with considerably different local contexts, it would be sensible to develop PED definitions in the form of an adaptive framework. This review marks the start of a quest for a universal framework of PED definitions that addresses the existing challenges. The goal is to provide the evidence base for policymakers and other relevant stakeholders in strengthening the PED concept and ease its implementation.

- Design issues for net zero-energy buildingsPublication . Aelenei, Laura Elena; Aelenei, Daniel; Goncalves, Helder; Lollini, Roberto; Musall, Eike; Scognamiglio, Alessandra; Cubi, Eduard; Noguchi, MassaNet Zero-Energy Buildings (NZEBs) have received increased attention in recent years as a result of constant concerns for energy supply constraints, decreasing energy resources, increasing energy costs and rising impact of greenhouse gases on world climate. Promoting whole, building strategies that employ passive measures with energy efficient systems and technologies using renewable energy, became a European political strategy since the publication of the Energy Performance of Building Directive recasr in May 2010 by the European Parliament and Council.
- Design issues for net zero-energy buildingsPublication . Aelenei, Laura Elena; Aelenei, Daniel; Goncalves, Helder; Lollini, Roberto; Musall, Eike; Scognamiglio, Alessandra; Cubi, Eduard; Noguchi, MassaNet Zero-Energy Buildings (NZEBs) have received increased attention in recent years as a result of constant concerns about energy supply constraints, decreasing energy resources, increasing energy costs and the rising impact of greenhouse gases on world climate. Promoting whole building strategies that employ passive measures together with energy efficient systems and technologies using renewable energy became a European political strategy following the publication of the Energy Performance of Buildings Directive recast in May 2010 by the European Parliament and Council. However designing successful NZEBs represents a challenge because the definitions are somewhat generic while assessment methods and monitoring approaches remain under development and the literature is relatively scarce about the best sets of solutions for different typologies and climates likely to deliver an actual and reliable performance in terms of energy balance (consumed vs generated) on a cost-effective basis. Additionally the lessons learned from existing NZEB examples are relatively scarce. The authors of this paper, who are participants in the IEA SHC Task 40-ECBCS Annex 52, “Towards Net Zero Energy Solar Buildings”, are willing to share insights from on-going research work on some best practice leading NZEB residential buildings. Although there is no standard approach for designing a Net Zero-Energy Building (there are many different possible combinations of passive and efficient active measures, utility equipment and on-site energy generation technologies able to achieve the net-zero energy performance), a close examination of the chosen strategies and the relative performance indicators of the selected case studies reveal that it is possible to achieve zero-energy performance using well known strategies adjusted so as to balance climate drivendemand for space heating/cooling, lighting, ventilation and other energy uses with climate-driven supply from renewable energy resources.
